Specification of Letters Patent No. 5,747', dated September v5, 1,848.

To all 'whom t may concern:

Be it known that I, JOSEPH FIELEMEIER, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful improvement in machines for cutting Jigures of any required form out of veneering, and other thin articles fqr inlaying :and ornamenting furniture and other articles, which is described as follows, reference being had to the anneXed drawings of the same, making part of this specification.

Figure l is a perspective view of the machine, in a position ready to cut t-he veneering. Fig. 2 is a vertical cross sect-ion of ditto-through the center. Fig. 3 is a horizontal section through the horizontal plate G. Fig. 4l is a top view of the inner clamp plate detached from the machine, which is the shape of the. ligure intended to be cut. Fig. 5 is a top view of the inner and outer clamp plates the single line between them representing the form of the cutters and their relation to said plates when adjusted for operation. Fig. 6 is a vertical cross section through the block and metallic plate, cutters, clamp plates, &c., showing the veneering in a position to be cut and the machine ready for operation. Fig. 7 is a plan of the cutters the dotted lines showing the metallic plate into which they are embedded.

vFig. 8 is a view of a cast iron plate having ornamental ridges formed on its face corresponding with the plumage of an eagle for branding the figure cut from the veneering. Similar letters of reference in the several figures refer to corresponding parts. v

The nature of this invention consists in cutting figures of any required formfoutof veneering or other thin article, by means yof f steel cutters, corresponding in form with the figure to be cut, and firmly embedded in the lower surface of a leaden or other metallic plate fastened to a horizontal block of wood, arranged between upright guides, secured to another horizontal block, forming the bed or table, between which and the cutters the veneering or other article to be cut is placed. Said block and plate of cutters being raised and forced down upon the veneering by means of a vertical screw work-` ing in a female screw formed in a iXed cross piece of the frame, and attached at its lower end to a casting secured to the blocl'and plate-the veneering being held'firmly during the operation of cutting, and disengaged from the cutters withoutbreaking the edges of the figure by means of clamp plates arranged between the veneering and Aplate cut-- ters and operated by a `combination ofv screws, plates, androds, in the manner hereafter described.

The' base A of the machineconsists of an oblong or square block of wood, on each side of which is secured a vertical metallic guide post B made V shaped on its inner edge and yheld firmly by curved braces C and a cross bar D extending from vone to the other. Between these guides is arranged a horizontal leaden or other metallic'plate 4E having a set of steel cutters F Figs. 2, 5 and 7 ,corresponding in shape with `the ligure to be cut embedded in its lower surface which leaden plate is secured to a similar shaped' plate G of iro-n vplacednltwtween it and a block of wood Himmediately above it by screws I in such manner that it can be rey moved at pleasure and another one having differently formed cutters inserted 'in its place. This block and plate of cutters thus occasion may require, by means of a vertical screw K turning ina female screw inV lower end working Yin a similarly formed cavity in the right vangled cross bars `L secured on top of the block H-said block and plates being guided in their movements by.

they shaped guides B formed on the inner sides ofthe posts yand entering corresponding depressions in theends of one of the cross bars. .a y 1 i Two horizontal clamp plates M, N, Figs.'`

l, 2, and 5 kare placed between the horizontal Y:so secured together are raised and lowered, as

base block A of theiframe and the metallic, Dlate- E "of thek cutters F for-the purposenof holding the Vveneering during'the operationY x of cutting,and disengaging the same from thecutters withoutbreaking the edges after the figures are out.

The'larger or outer plate yM is made` 'square on the outer edges, and curved on its inner edges to theform ofr an eagle, to

correspond with the eagle form of the cut" ters F and the edges of the inner clamp plate whichare also of the form of the outline of an' eagle-the edges of the said. smaller or inner clamp plate are curved to correspondl with the curvature of the inner "edges of the outerfplate in order to leave a space between the inner edges of the outer plate M and the inner plate N just wide enough to allow the cutters F to pass through without touching either plate as aforesaid, and as represented at F in Fig. 5. These plates M N are held in their proper places by means of a series of upright pins or rods m, n, secured to their upper sur-` faces and extending through openings in the plates E G and being in length a litt-le greater than the thickness of the plates E G, block H and veneering, so that whenthe veneering V is placed in the machine and before it is cut (as represented in Fig. 6) their upper ends shall touch the under surfaces of four horizontal metallic plates P P P P arranged at the corners of the block H andheld in their proper positions bypins Q, projecting from their lower surfaces and entering openings in the block H. The plates P P P P are held down upon the rods m n by the triangular plates R which are attached to the lower ends of the screws S that turn in female screws in arms T eX- tending horizontally from the sides of the fixed cross head D which is fastened to the permanent base A by the posts B and the braces C. The triangular plates R are `to be raised or lowered by the screws S in order to adjust the plates-hl N for clampingv veneering of various thicknesses. The clamp plates may be formed from a single plate by drawing thereon the intended de-l sign to be cut from the veneering and d ividing the plate by cutting it through along said lines and then filing the cut edges till a space shall be formed between them (when the plates are again placed together) sufliciently large to admit the cutters (made of thin steel watch-springs) to work freely between them.

The operation of the machine is described as follows. The sheet of `veneering V is placed between the clamp plates M N and the base `block A and the clamp plates broughtdown upon it firmly by turning the screw S which cause thetriangularplates R to descend upon the,V square plates P and press them hard down upon the stems or rods mn'of the clamp plates M N-the guide rods Q, attached to the under sides of the plates P preventing any Vhorizontal movements in said plates. The screw K is then turned which causes the crossed frame L and'all the appendages suspended to its lower end to descend carrying with it the metallic stock L and cutters F-which latter are forced through the veneering, the base A, guides B, cross head D, screws S, plates R and M, N and stems m n remaining stationary. The motion of the screw K is then reversed which causes the aforesaid movable frame and cutters to rise and leave the veneering without breaking the edges of the ligure cut by means of the'clamp binding the edges ofthe cut portions of the f veneering. To remove the veneering all the p plates must be raised which 4is eiected by turning the screws. removed and another sheet put in its place and operated on in the same manner. The stamp Fig. 8 (previously heated) is then rlhe veneering is then applied to the cut figure to brand it with the i devices on its face, such as the pinions, talons, eye and shield, &c., of the eagle.

Any description of figures may be cut and stamped in the saine manner by changing i the form of the cutters, clamp plates, brands & c. thus cut and branded is performed in the usual manner.

l/Vhat I claim as my invention and desire y the combined posts and vertical guides as described.

3. I claim the combination of the leaden,

f iron, and wood plates with the steel spring cutters bedded into the leaden plate as described.

In testimony whereof I have hereunto signed my name before two subscribing witnessesthis 17 day of `September A. D. 1847.

` JOSEPH FIELEMEIER.
